一、菜单 (1)选择菜单(OptionsMenu) 第一种方法: 1、在res目录下建立一个名称是menu的文件夹; 2、在menu下面建立一个XML文件(默认就是menu的类型) 3、在建立的XML文件中添加菜单的选项 XML中有很多的属性: <1>android:orderInCategory 表示的意思是:确定当前的item在整个item中所在的位置(数字越小越靠前) <2>android:title 确定选项的内容 <3>android:id 设置选项ID <4>android:icon 设置选项的图标 <5>android:showAsAction 设置图标的显示方式 <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/select_01" android:orderInCategory="1" android:title="马超"/> <item android:id="@+id/select_02" android:orderInCategory="2" android:title="马云禄"/> <item android:id="@+id/select_03"

Android 开发中踩过的坑之十二: ListView中的焦点抢夺

旧巷老猫 提交于 2019-12-06 23:55:07
当ListView设置了OnItemClickListener, Item项里的View设置了OnClickListener时, 经常遇到某一个Listener失效的现象. 根本原因是焦点的问题, 当item项目中某个View能够获取焦点时, 根据View焦点传递的规则会优先接受点击事件, 如此就会导致ListView的OnItemClickListener失效. 因为能够自动获取焦点的View有优先获取点击事件的权利, OnItemClickListener是在Item的父节点, 所以它是最后一个处理点击事件的(虽然最先接收, 但是先分发给子View, 子View处理完后, 最后自己处理). 如果子View处理并消化了点击事件, 那么OnItemClickListener久失效了. 解决的方法: 1 你可以放弃 OnItemClickListener, 只是用 OnClickListener. 2 检查你的Item 里, 时候有focusable=true 和 focusableInTouchMode=true的View. 如果有, 把他们都设置成false. 来源: oschina 链接: https://my.oschina.net/u/1393188/blog/518080

jQuery Dollar Sign Confusion

泪湿孤枕 提交于 2019-12-06 20:55:40
问题 I'm a bit confused regarding the dollar sign in jQuery, and was hoping someone could help me out. I have the following function declaration: $(function() { $( "#create-discussion" ).button().click(function() { alert("Clicked"); }); $( "#listitems tr" ).click(function(event) { alert("clicked"); }); }); For some reason, the first function declaration for the "create-discussion" button works perfectly; when clicked, a popup appears. However, the second one does not work, and no popup is

<tr> onClick not working

こ雲淡風輕ζ 提交于 2019-12-06 19:06:01
问题 I want to turn my table rows into links using JS. I have it looking like this: <tr onClick='javascript:window.location.href='url';'> However, when I try to click, it doesn't go the page as I want. In fact, clicking seems to have no action. Any help? Edit: As for the quotes, I forgot to mention that I'm echoing this with PHP. Here's my updated code: echo "<tr onClick='window.location.href='url?id=" . $var . "';'></tr>"; Should I be doing some sort of escaping like /" in this case? 回答1: First

nvd3.js : unable to bind onClick event with the data points in the svg

问题 I am trying to bind the datapoints with the onclick event, so that I could display a overlay box with some additional details and links. I'm using the .nv-point class to access the datapoints. The problem is that I'm unable to register the onclick event to those datapoints.
